将拉曼放大添加到传输系统中，以提供更高的功率预算，从而允许通过TDM或WDM将容量提升四倍。实验验证了时分复用从2.5 Gb/S升级到10 Gb/S，以及波分复用从单个10 Gb/S通道升级到4个10 Gb/S通道，功率预算分别提高了7.4dB。对于不需要改变光纤跨度的已安装系统，拉曼增益是一种有吸引力的升级方法。
Raman amplification is added to a transmission system to provide an increase in power budget allowing for a four-fold upgrade in capacity either by TDM or WDM. Here, a TDM upgrade from 2.5 to 10 Gb/s and a WDM upgrade from a single 10-Gb/s channel to four channels of 10 Gb/s each were experimentally verified with an improvement in the power budget of 7.4 dB. Raman gain is an attractive upgrade method for installed systems requiring no changes to the fiber span.
